Experiment of the Vibration Characteristic of the Turbine Blade With Zigzags Shroud

According to characteristic of the turbine blade with zigzag-shroud and the lab condition,the clamp to the blade was designed,three kinds of experiment model was used,single-blade model,three-blades model and several-blades model,and the modal experiment and harmonic experiment was finished for analyzing the vibration characteristics of the turbine blades with zigzag-shroud in this paper.Meanwhile the modal vibration and the vibration damping of the blade with zigzag-shroud was researched.In the end,the effect of zigzag-shroud on the vibration of the blade was discussed based on the experiments.
